On November 16, BYD held the 3 millionth new energy vehicle offline launch conference, known as the "highlight moment of Chinese brands". BYD also undoubtedly firmly sits in the "top position" of China's new energy vehicles. Today, BYD's overseas footprint has spread to more than 70 countries and regions around the world. The Han EV and Tang EV, which are located in the European market, can even "fight with the traditional fuel luxury brand BMW Mercedes-Benz .
Many people saw BYD's current achievements and couldn't help but sigh: When did BYD, a battery-making company, start to embark on the fast lane of new energy vehicles? However, when you look at the development history of BYD's new energy vehicles, you can find that this is really more inspiring than the "counterattack road" of the protagonist of the novel.
, which was jokingly called "the big fool", BYD new energy vehicle
When it comes to the development of China's new energy vehicles, we have to mention the "new energy vehicle plan" mentioned by Qian Xuesen in a letter to the central government in 1992. Before that, the energy crisis that broke out in the 20th century 0s and 1980s made Western countries have begun to pay attention to the research and reform of new energy vehicles. In 1976, the US Congress passed the "Research, Development and Proof of Electric Vehicles and Compound Vehicles". In 1990, the European "Urban Electric Vehicles" Association was established. Under the strong suggestion of Mr. Qian, in 1996, my country also listed electric vehicle as a major national scientific and technological project during the "Ninth Five-Year Plan" period.
But how should new energy vehicles be built? Western developed countries obviously have a more say than my country, which has not yet been studied and understood by fuel vehicles. Moreover, in that era, domestic car companies were still studying the three major items of fuel vehicles. Santana on the street is still a rare thing. Which car company dares to eat this first bite of crab?
is BYD.
In 2003, BYD, a major lithium battery manufacturer, acquired Qinchuan Automobile and began to move from making batteries to building cars. The BYD F3 launched by this latecomer of car manufacturing has become a hot-selling model. In 2007, BYD Auto relied on the affordable price F3 just gained a foothold in the automotive industry. BYD Chairman Wang Chuanfu shouted the slogan "Rely on electric vehicles to achieve the world's first sales in 2025". For a time, "big fools" comments emerged one after another.
Anyone who knows Wang Chuanfu knows that he is a technical entrepreneur with strong scientific research and execution ability. It is not groundless that he can shout this slogan. At this time, Wang Chuanfu had already developed the world's advanced electric motor . The BYD F3E, which was unveiled at the 2006 Beijing Auto Show , is BYD's first pure electric vehicle. However, because the problem of pure electric vehicle supporting facilities is difficult to solve, in December 2008, BYD took the lead in launching the plug-in hybrid F3 DM.
at that time BYD F3 DM was equipped with BYD's first-generation DM hybrid system. This platform is undoubtedly a technology that surpasses the times in terms of technology. The first-generation DM hybrid system incorporates a 1.0-liter three-cylinder engine into two motors and a reducer, realizing three driving methods: pure electric, extended range (the engine drives the generator to charge the battery), and hybrid. Various modes switch to each other, saving fuel to a large extent (fuel consumption per 100 kilometers fuel consumption 2.7L).
But technology always relies on materials to achieve design effects. The high-end DM system has a strong sense of cease and insufficient power in actual use (10.5 seconds per 100 kilometers). The maximum speed is subject to the maximum speed of the motor. The most important thing is that it is 80,000 yuan more expensive than the fuel version of F3. Even under the policy of Shenzhen subsidy of 80,000 yuan, this super-era hybrid car, , bought less than 300 vehicles, and almost no one cares about it.
BYD
, which relies on the first generation of DM technology to make a comeback. After launching F3 DM, BYD launched the familiar e6 in 2010. BYD has high hopes for this car that is used for taxi, and it is also the first car that pure electric cars have begun to approach consumers' minds. Unfortunately, BYD's financial situation at that time experienced a serious crisis, which once made BYD crumbling.
After that, BYD new energy vehicle began to gradually develop, especially after BYD proposed the "542 strategy" in 2014, in 2015, Qin, Tang and e6, the efforts of BYD's new energy vehicle sales exceeded 60,000 vehicles throughout the year, becoming the leader of domestic new energy vehicle companies, and even had no competitors in the world. At this time, BYD's new energy vehicle strength began to be recognized.
Unexpectedly, the "subsidy fraud" of new energy vehicles in 2016 directly caused the entire domestic new energy vehicle. In order to defraud high state subsidies, a large number of car companies assembled inferior pure electric vehicles, which suddenly made many consumers feel hurt by new energy vehicles, and directly had a huge negative impact on the sales of new energy vehicles in the next few years.
BYD's new energy vehicles are also moving forward with heavy burdens amid doubts and are moving forward steadily. However, in 2018, BYD encountered the "tough" rival of Tesla , which was the "tough" of the sales champion, and its position changed hands almost instantly. In 2017, the lithium battery business, which has always been the mainstay of the mainstay, was also surpassed by the "rise" Ning's era. At this time, BYD needs a "sharp blade" to break the current situation.
So in 2021, BYD DM-i super hybrid technology appeared.
If the emergence of the new generation of Tang in 2018 marked the implementation of the first luxury model in the new era of car manufacturing, Han, which was equipped with " blade battery " for the first time in 2020, became BYD's biggest publicity point at that time, but the real goal of making BYD's new energy vehicles go from a monthly sales of over 10,000 to tens of thousands or more or tens of thousands of yuan, is the first achievement of the launch of DM-i technology in 2021.
BYD's DM-i technology has compressed the additional cost incurred by the hybrid system, equating the price of hybrid vehicles with fuel vehicles of the same level, which directly makes consumers unable to do the "multiple-choice questions". At the same price, who wouldn't want to buy a more fuel-efficient hybrid vehicle?
BYD DM-i super hybrid technology is essentially continuing the first generation of DM technology in 2008, because this generation of DM technology has the structural advantage of reducing the cost of hybrid vehicles. Compared with the second and third generation DM technologies, multi-speed transmissions and star wheels can be cancelled, and the engine and motor are driven in series are used, which also reduces the battery's high-speed power supply pressure.
Of course, the huge material disadvantages of the first generation DM technology must also be compensated. Simply put, the secondary conversion of energy in series drive requires a higher efficiency engine. High-efficiency engine needs compression ratio to achieve, and high compression ratio needs to solve the problem of knocking in the engine cylinder, etc. In order to solve these problems, BYD has developed hundreds of patents in the front and rear, and has profound technical precipitation, making the 1.5L Xiaoyun engine with thermal efficiency reaching 43% become a reality.
Since then, BYD's new energy vehicle sales have completely ushered in a "bomb-blasting" increase, from a monthly sales of tens of thousands to 100,000, to overtaking Tesla, to a monthly sales of 200,000, and to a cumulative sales of 3 million vehicles today.
The future BYD will be even more "terrifying"
BYD Chairman Wang Chuanfu also previewed the brand of Yangwang at the press conference, which will officially lead BYD into the field of million-level high-end automobiles. The first model is expected to be officially launched in the first quarter of 2023. Many people will think of the "traditional skills" of improving the grade of domestic cars - pile materials, and pile various functions and interiors to the greatest extent. However, as for BYD, the probability is very small, because as a technology car company with ,426 patents, BYD may give us several "big surprises".
For example, the 800V voltage platform, the 800V voltage platform has always been a hot topic in pure electric cars. We all know that the higher the voltage, the faster the charging speed will be when the current upper limit is a certain level. At present, many new energy vehicle companies are solving the problem of slow charging speed of high-capacity batteries. Since ordinary charging piles on the market are 500V voltage, they cannot charge batteries with a voltage of more than 500V voltage at all. So car companies such as Tesla have begun to build their own "super charging piles" with high output voltages, and for example, Ideal directly adopts the battery swap mode. These car companies are doing these tricks around the bush, which is essentially because they cannot solve the boost charging technology.
But BYD has the drive multiplexed boost charging technology. Simply put, it is the technology of using the transformer principle to achieve low voltage boost through the coil in the motor.
At present, BYD pure electric car power battery voltage is more than 650 volts and the charging voltage is more than 700 volts. It is not difficult to achieve 800V voltage in the field of million-level high-end automobiles. Of course, the current leader of the 800V voltage platform is Porsche . The value can be felt directly.
As for how many black technologies that other car companies can "look up to" are there, we will only know after the announcement next year. Let's wait and see!
